Summary Introduction
To review:
The given blank space in the statement using the following ECG graph.
QRS duration: __________ QT duration: ____________
Ventricular rate and rhythm: _____________
Atrial rate rhythm: _____________________
PR interval: __________________________
Interpretation: ________________________
Introduction:
The process named electrocardiography (ECG) is used to monitor a patient’s heart rate. It records the electric signals that are produced by the heart in the form of wave components, such as P, Q, R, S, T, and U. The electric signals are recorded by 10 electrodes that are placed over the patient’s body.
